The pedigree research was carried out by Mr. Martin Meehan utilizing Betham’s Genealogical Abstracts of Irish Prerogative Wills and Administrations ca. 1536-1810, The Crosslé Genealogical Abstracts ca. 1620-1804, and also Information from the Registry of Deeds ca. 1712-1900. Mr. Patrick O’Flynn assisted with pedigree research prior to Edmond O’Flyn and the printing of their results in a private book form.Edmond O’Flyn, who lives near Ballinlough, is the present O’Flyn, but he retains but a very small portion of the territory of Sil-Maolruain.
Eóchád Tírmchárnae was the third son of Fergus and the progenitor of the Uí Briúin Aí branch, of which the Ó Conchobair Dond were supposed to be a sept, but which Y-DNA testing proved otherwise. Please see viewtopic.php?p=2201#p2201. However, the Mac Diarmata and other well known Síl Muiredaig families are showing up under the R-FGC5939.2 clade. Please see viewtopic.php?p=1659. The Síl Muiredaig became the dominant branch of the Uí Briúin Aí. Although the Síl Maíl Rúana are recorded as an earlier branch than the Síl Muiredaig, the Síl Maíl Rúana Ó Flainn now joining the Síl Muiredaig families provides effectively irrefutable evidence that R-FGC5939.2 is the Maicne Eócháda Tírmchárnai clade.
Currently there are two subclades of the R-FGC5929.2 clade, but neither of them supports the Síl Maíl Rúana genealogy. Eóchád Tírmchárnae's single son Áed Flaithem/Abrat, who was a King of Connacht, is recorded as having THREE sons. His son Curnán is the putative progenitor of the Síl Maíl Rúana. We are waiting to see if Mr. O’Flynn finally gives us the third subclade under the R-FGC5929.2 clade or whether we uncover another divergence with the genealogies.
Regardless, Curnán's story is a tragedy worthy of William Shakespeare. He was under the protection of St. Columb Cille when Diarmait son of Cerball of the Conall Eirr Bríg Uí Néill and High King of Ireland slew him for unknown reasons. This resulted is a war between King Diarmait and King Áed Flaithem/Abrat of Connacht and other Uí Néill septs in which King Diarmait was defeated. King Diarmait did not die until a few years later.

AT559.4
The death of Curnán son of Aodh son of Eochaidh Tirmcarna, by Diarmaid son of Cearball while under Columcill's protection, and that is one of the causes of the battle of Cúil Dremne.
AT560.1
The battle of Cúil Dremne gained over Diarmaid son of Cerball. Forgus and Domnall, two sons of Muircheartach mac Erca and Ainmire son of Setna, and Ninnid and Duach and Aodh, son of Eochaidh Dryflesh, king of Connacht, were victors through the prayer of Columcill, who said:AT561.1O God,
Why keepest though not the mist off from us,
if perchance we may reckon the number
of the host that deprives us of judgments.
A host that marches around a cairn,
'Tis a son of storm that betrays them.
He is my druid that denies me not,
The Son of God it is who will work with me.
Beautiful it makes the onset,
Baetán's steed before the host,
It seems good to Baetán of the yellow hair,
It will bear its burden upon it.
The battle of Cúil Uinsenn in Tebtha, gained over Diarmaid son of Cearbhall by Aodh son of Brénann, king of Tebtha, in which Diarmaid took to flight.
AT563.4
Diarmaid son of Cearbhall was killed in Ráth Bec in Magh Line by Aodh Dubh son of Suibne Araidhe, king of Ulster, and his head was taken to Cluain and his body was buried in Connere. To whom two sons of Mac Earca succeeded i.e. Forgus and Domnall.
